Product Details


Astm Stainless Steel Stainless Pipe is a kind of hollow long steel, a large number of used as a fluid pipeline, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength at the same time, the weight is lighter, so also widely used in the manufacture of mechanical parts and engineering structures.Also commonly used for the production of various conventional weapons, barrels, shells, etc.Today small make up for you to introduce the stainless steel tube specification table and stainless steel tube implementation standards.

Astm Stainless Steel Seamless Pipe

Astm Stainless Steel Stainless Pipe with a hollow section, Seamless without seams around it.Slit pipe is generally rolled into a steel cylinder welding.There is a difference between a seam tube and a seamless tubeConcentricity: seamless tube manufacturing process is under the temperature of 2200 ° f stamping out a hole in the stainless steel billet, under the high temperature, and tool steel after the stamping and drawing become soft and spiral forming from the hole.In this way, the wall thickness of the pipe is uneven and the eccentricity is high.Thus astm allows a greater wall thickness difference for seamless tubes than for slit tubes.Slit tubes are made from precision cold rolled sheet (4-5 feet wide per roll).These cold rolled sheets usually have a maximum wall thickness difference of 0.002 inches.The steel plate is sheared to the width of d, where d is the outside diameter of the pipe.The tolerance of the wall thickness of the slit tube is very small, and the wall thickness of the whole circumference is very uniform.

The steel plate is sheared to the width of d, where d is the outside diameter of the pipe.The tolerance of the wall thickness of the slit tube is very small, and the wall thickness of the whole circumference is very uniform.Welding performance: generally there are some differences between the chemical composition of the seam pipe and the seamless pipe.The composition of the steel used to produce seamless tubes is only to meet the basic astm requirements.The steel used to make the tubes contains chemicals suitable for welding.For example, silicon, sulfur, manganese, oxygen and triangular ferrite and other elements in proportion to the mix in the welding process can produce a kind of easy to transfer heat welding fusion, so that the whole weld penetration.Steel tubes lacking the above chemical components, such as seamless tubes, will produce various unstable factors in the welding process, not easy to be firmly welded and not fully welded.
